-LRB- CNN -RRB- -- The search continued Tuesday for as many as 67 people missing after a boat carrying about 200 Haitians capsized , the U.S. Coast Guard said .

The U.S. Coast Guard intercepted this crowded boat last week and repatriated its occupants to Haiti .

The boat overturned Monday off Turks and Caicos , a British territory about 550 miles southeast of Miami , Florida .

Searchers aboard boats and aircraft have rescued 118 passengers and found 15 bodies , said Petty Officer Jennifer Johnson , a Coast Guard spokeswoman , on Tuesday morning .

The Coast Guard described the boat 's occupants as migrants from Haiti . The overcrowded vessel was believed to have set sail from the Haitian port of Cap Haitien , the Turks and Caicos Sun newspaper reported .

The search resumed at dawn Tuesday after being suspended because of darkness Monday night , Johnson said .

The Coast Guard is contributing one boat , the 210-foot cutter Valiant , and three aircraft to the search , Johnson said . The aircraft are a Falcon jet out of Miami , an HH-60 helicopter and a slow-flying C-130 cargo plane out of Clearwater , Florida . Watch Coast Guard rescue Haitians after boat capsizes ''

`` If the weather and conditions are right , -LSB- the C-130 -RSB- can fly really low , '' Johnson said . `` It makes a fantastic search aircraft . ''

Turks and Caicos authorities are using small boats in the search , she said .

About 70 people were plucked Monday from a reef near the island group , authorities said . Four other bodies were found , though it was unclear which authorities located them .

A nurse at Myrtle Rigby Hospital in the Turks and Caicos said that about 70 people were brought there , including four who had died .

Five people were admitted to the hospital , and the others had minor injuries , the nurse said .

The Coast Guard said it intercepted another `` grossly overloaded '' boat , with 124 Haitians aboard , late last week in the same region . Those migrants were returned to Cap Haitien on Monday .

Overloaded vessels can quickly lose stability and capsize , sending migrants into the water , a Coast Guard release said .
